9/8/2016 Digital Imaging Digital Imaging Purpose & Uses ‐detect lesions, disease, and conditions of the teeth and surrounding structures ‐to confirm or classify suspected disease ‐to provide information during dental procedures ‐to evaluate growth and development ‐to illustrate changes secondary to caries, perio disease, or trauma ‐to document the condition of a patient at a specific point in time Fundamentals & Key terms Sensor Digitized Pixel CCD Resolution USE RECEPTOR 2 TYPES: • Direct • Indirect *we have both 1 2 Digital Radiography Digital Imaging Advantages v/s Disadvantages 2 Types of Digital Imaging • Direct (SENSOR) • Indirect this includes Storage Phosphor (Scan‐ X) QUESTION TO DISCUSS: IS IT LESS EXPOSURE? CBCT: Cone Beam-Computed Tomography Cone Beam Dental Imaging 3‐D Cone‐beam CT imaging: Rapid scan (less than 1.5 minutes) lower dose than CT scan superior to panoral radiograph (but inferior to CT) dosage comparison‐ panoral 6‐20 mSv/CBCT 135 mSV; CT 314‐2000 mSv (*mSV measures radiation just as rem or mrem) Cost $$ machines average 100k‐250k (more cost for patient too) Have to be reviewed by radiographer Great for implants, pathology, trauma, surgery https://www.youtube.com/watch?v=CKfOUhh7_‐M 1 9/8/2016 SAFETY & INFECTION CONTROL Radiation Comparison Chart Sources of Radiation Amount of radiation Radiation Comparison Chart **Considering the average person is exposed to 200‐450 mrem radiation a year, the amount of radiation received during dental x‐rays is minimal Daily exposure to natural radiation 0.8 mrem Single intraoral x‐ray digital 0.325 mrem Less than half of 1 day Bitewings (4 films digital) 1.3 mrem about 1.5 day Intraoral full‐mouth digital 6 mrem about 7 days 2‐D pan 1.4‐2.4 mrem about 2‐3 days 3‐D Cone Beam 8.7 mrem about 11 days Head CT 86 mrem about 108 days CT Full Body 1000 mrem about 3 years Flight from New York to LA 2‐5 mrem about 3‐6 days All up to you!
